What if, by preserving your body long enough, you can hold on to life until eternal youth is invented? And then laugh at all those people who killed themselves with fun while you run around for eternity

we might be able to adapt for a little bit, but our brains would become cluttered with memories, and as we get older our sense of time supposedly gets ****** up, and time feels like it goes by faster and faster

Run around for eternity? Ok.
Your first partner on the trip of eternity. You love her so. Will never leave her side. 60 years has passed, you are still young. She, is on her death bed. Will never get to walk into the gates of eternity.

Nope. Would rather die with the gal I love than continue breathing on this god awful place.
